Tim Burton work

Hopefully, most of you will have heard of Tim Burton, well known for his films and animations, such as The Corpse Bride, A Nightmare Before Christmas and the recent Alice in Wonderland. These illustrations are characters from Tim Burton's work. I drew them all mostly in fine liner pen or a regular HB size pencil. To view more of Tim Burton's work, you can visit his website, here.

This last piece I'd seen somewhere on the internet a while ago and decided to draw it for myself. I cant seem to find who drew it originally, so for anyone reading this who recognizes the drawing, please help me find the artist so that I can credit them. Thanks in advance.
